Flowmaster V7 Gas Turbine

Flowmaster V7 Gas Turbine is an industry specific thermo-fluid system simulation software tool. Built upon the Flowmaster V7 platform, V7 Gas Turbine combines the same proven architecture with optional Swirl and Heat Transfer solver capability of secondary air system modelling. The advanced GUI with specific gas turbine component libraries and cavity model creation wizard enables users to build networks and run simulations quicker and easier than ever before.

Many of today’s leading gas turbine manufacturers use Flowmaster to validate designs and run simulations early in the development process to maximize system efficiency, minimize testing costs, improve quality, promote design repeatability and ultimately reduce gas turbine development cycles. Customers include: Kawasaki Heavy Industries, GE, Siemens, Mitsubishi Heavy Industries, Hitachi and Alstom.

Gas Turbine Modelling Packages:

Flowmaster V7 Gas Turbine features a range of specific modelling packages:

Gas Turbine - General Modelling PackageFlowmaster V7 Gas Turbine enables users to predict lubricant pressure, flow rates, temperatures and other performance parameters as well as specify and optimise component sizes and understand the effect of component changes on the entire system.

Fuel systems must deliver the fuel at the required flow rate, temperature and pressure. Utilising V7 Gas Turbine users can predict fuel system behaviour for critical design cases and ensure adequate fuel flow and pressure, accurate fuel metering and control pressure transients. Further fuel system modelling capability is available in the Gas Turbine - Suite Modelling Package.

Gas Turbine - Secondary Air Modelling PackageUnderstand the swirl characteristics (pressures, temperatures and flow rates) of complex secondary air flow paths based on 2D geometry cross-sections. Flowmaster V7 Gas Turbine utilizes a swirl solver and heat transfer solver to assess the impact of thermal conditions by modelling both frictional and wall surface heat transfer with the flexibility for companies to include their own proprietary correlations for flows and thermal effects through these rotating passageways.

Flowmaster V7 Gas Turbine also reports the velocity effects of combined flows so that the effect of pre-swirl nozzles and impingement losses can be understood.

Gas Turbine - Suite Modelling PackageThe Flowmaster Gas Turbine Suite combines the functionality of the Secondary Air systems modelling package, the Gas Turbine General systems modelling package and Multi Fluid Simulation advanced functionality. Multi Fluid Simulation enables users to simulate the mixing and/or separation of multiple liquids or gases, This capability enables fuel system engineers to model the vent lines and inerting systems of gas turbine fuel systems and also track feedstock concentration changes.

The Gas Turbine Suite also includes advanced Psychrometrics modelling capability which allows users to model and simulate accurately the moisture and humidity changes as air flows in the gas turbine auxiliary systems.

Flowmaster V7 Gas Turbine Features in Detail:

Gas Turbine tailored components and modelling toolsFlowmaster V7 Gas Turbine provides an industry tailored catalogue of gas turbine components on top of the existing comprehensive library of standard fluid and thermal components available in Flowmaster V7. These components include a brush seal, labyrinth seal, rotating cavities, annular passages and specialised orifices, all of which are customisable.

Intuitive Interface and Short Learning CurveThe graphical user interface is designed to optimise workflow through a streamlined catalogue and performance data structure, drag and drop component placement, dynamic data filters and data input wizards, resulting in faster model creation and data input while minimising margin for error. Also included is a specialised Cavity Wizard for creating secondary air system cavities to help users to input the complex geometrical characteristics required to model the rotating air flow that occurs in cavities formed in the rotor and stator disks.

Advanced analysis tools for the Gas Turbine industry

• Swirl Solver – Flowmaster V7 Gas Turbine features an integrated swirl solver which calculates the swirl generated by rotating components and geometrically induced swirl (such as that generated by preswirl nozzles). It also tracks how the swirl is propagated downstream including how it is either enhanced or degraded by the other downstream components.

• Heat Transfer Solver - Flowmaster V7 Gas Turbine utilises a heat transfer solver to simulate the air flow and heat transfer in the secondary air systems of a gas turbine. This capability is flexible enough to allow companies to include their own proprietary correlations for thermal effects through these rotating passageways.

• Multi-Fluid Simulation - This advanced functionality enables the modelling of mixing and/or separation of multiple liquids or gases. Users are able to calculate the fluid properties of combined liquids or gasses which is important when modelling steam injection in combustors and fuel systems for power generation turbines utilising syngases.

Design Collaboration & Secure Data ManagementBuilt upon a powerful relational database, organisations have the ability to store, share and track project data faster and more securely than ever before, allowing far greater collaboration across gas turbine project teams. Organisations can also capture and share knowledge gathered from experienced technical specialists, passing on best practice methodologies to others in the organisation.

IntegrationThe Flowmaster V7 ‘Open API’ structure allows you to integrate Flowmaster V7 Gas Turbine into your current product development process including in-house codes, CAE, manufacturing and optimisation tools. This allows organisations and supply chains to gain secure and fast access to relevant data.

By linking Flowmaster into your PLM system, data and simulation reports are available at any given point during the development lifecycle of a gas turbine, clearly communicating project status alongside all other processes which can lead to improved decision making.
